The main reason people opt-out of your mailing list is because you are not offering anything of value to them, whether it be through sample products, free information that solves a problem, or simply offering them a free ebook.

Another reason people will opt-out is because you send too many emails throughout the week and you’re cluttering up their inbox with offers, sales pitches, and things that look like spam.

Then there are those people out there who really don’t want to be on anyone’s list, and might be willing to look you up again if they need something from you.

The best way to keep them on your list is to keep them engaged, offer them true value, develop a relationship with them through personable emails, and send out just one or two emails a month unless you’re in a business where it is necessary to send more and your subscribers expect that from you.
